Red Tani of Filipino Freethinkers calls Natasha Campbell-McBride a pseudo-scientific quack

Red Tani wrote an article entitled Sotto’s Pseudoscientific Source: Who is Natasha Campbell-McBride?:

I don’t think so. As far as Sotto’s credibility goes, citing Dr. Natasha was even worse than plagiarizing Pope. Because Dr. Natasha is a quack. She is most known for inventing the idea that autism — and many other symptoms and diseases — is caused by bacteria in our gut, a condition she calls “Gut and Psychology Syndrome” or GAPS — because “gut bacteria” just doesn’t sound as scientific.

Since Ryan “Red” Tani, President of the Filipino Freethinkers, calls Dr. Natasha Campbell-McBride a pseudo-scientific quack which Senator Sotto cited, may we know what are the medical and scientific qualifications of Red Tani for making such statements? For Dr. McBride, her qualifications are clear from her website, Doctor Natasha:

“Dr Natasha Campbell-McBride is a medical doctor with two postgraduate degrees: Master of Medical Sciences in Neurology and Master of Medical Sciences in Human Nutrition.
She graduated as a medical doctor in Russia. After practising for five years as a Neurologist and three years as a Neurosurgeon she started a family and moved to the UK, where she got her second postgraduate degree in Human Nutrition.”

A simple check of Dr. Natasha Campbell-Mcbride’s publications in Google Scholar shows that she is not a quack, otherwise reputable medical journals would not publish her writings. I also tried to check Ryan Tani’s publication in Google Scholar, but I could not find any.
